Automatic Transmission/Transaxle: 5A-59
DTC Troubleshooting
Step Action Yes No
1 Was “A/T System Check” performed? Go to Step 2. Go to “A/T System
Check”.
2 Check pressure control solenoid valve resistance
1) Turn ignition switch OFF position.
2) Disconnect valve body harness connector (1), (2) on
automatic transaxle.
3) Check for proper connection to terminal of valve body
harness connector at “GRY” and “LT GRN/BLK” circuit.
4) Check resistance of pressure control solenoid valve.
Pressure control solenoid valve resistance
Between terminals of transaxle side valve body
harness connector: 5.0 – 5.6 Ω at 20 °C (68 °F)
Between terminals of transaxle side valve body
harness connector and Transaxle: Infinity
Is check results satisfactory?
Go to Step 3. Replace pressure
control solenoid valve or
valve body harness.
3 Check for pressure control solenoid valve circuit
1) Disconnect TCM connectors.
2) Disconnect valve body harness connector and TCM
connectors.
3) Check for proper connection to TCM at terminals “C34-
2” and “C34-4”. If connection is OK, check circuit for
open, short, and high resistance for the following circuit.
• Between “C34-2” terminal of TCM connector and “LT
GRN/BLK” terminal of valve body harness connector.
• Between “C34-4” terminal of TCM connector and
“GRY” terminal of valve body harness connector.
Are they in good condition?
Intermittent trouble or
faulty TCM. Check for
intermittent referring to
“Intermittent and Poor
Connection Inspection
in Section 00” If OK,
substitute a known-
good TCM and recheck.
Repair “LT GRN/BLK”
and/or “GRY” circuit.
